    3. INTRODUCTION This series of laboratory grade, switching mode, programmable power supplies are ideal for repetitive test routines in R&D, Production, Product Evaluation and various applications. Information appearing on the large back-lit LCD makes the panel controls simple and easy to use in spite of its sophisticated features. Because of the MCU (Micro-Controller Unit) and the related software, user re-calibration without opening the case is an added bonus.

    7. USING THE PRESET FEATURES PRESET PROGRAM SYMBOLS Program Unit is ready for inputting of a Preset Program Number (19). Recall Unit is ready for recalling a Preset Program Number. The unit can store nine preset voltage and current settings. Once programmed, these settings will be retained even when the unit is switched off.

  • Page 15: Operating The Timed Program

    Selecting Presets 1. Press the RECALL key The display will show Recall_ 2. Press the number key (1-9). The display will show the chosen Preset Number, its voltage and current level. 3. Press ENTER to activate .The unit will resume the chosen reset values. If during any of the above procedures, you fail to input a setting within 10 seconds, the unit will cancel the procedure and resume the previous settings.

  • Page 16: Running The Timed Program

    Note: A. Once the subprograms are filled, the unit will return to manual operation mode. Any subprogram with zero time period will become the Terminating Subprogram. For example, if you set the subprogram 7 with zero time period, all the subprograms after 7 (i.e. 8, 9, 10-19) become non-existent. The timed program will only cycle from subprogram 0 (STEP) to subprogram 6.

    8. MAINTENANCE 8.1 RECALIBRATION Introduction This in-case recalibration is to reduce the difference between the Set values and the displayed values on the LCD Display. You only use the recalibration when the difference is greater than 0.1V for voltage or -0.01A / +0.02A for current. The whole recalibration for voltages and current takes less than 15 minutes. It is performed by a proprietary software using regression algorithm.
